Abstract

Abstract: A new improved approach of testing powder method for rapidly determining nitrate content in fresh vegetable was studied. The results showed that the absorbance value at 538 nm had a good linearitywith the nitrate content in the range 0 - 20 mg/L with the relationship coefficient 0.9999, the recovery 97.7 % - 104.5% , and RSD 2.71% , when the extracting solvent 2% HAc in current method was substituted by H₂O, the ratio of testing powder consisting of citric acid monohydrate, manganese sulfate monohydrate, P-aminobengene sulponie acid anhydrous, N₂ (1-naphthyl) ethylenedianine dihydrochloride and zinc powder was 30∶4∶1.6∶0.8∶1, and the quantity added was 0.1 g. The nitrate contents in eleven vegetable species determined by this method were not significantly different from those determined by the national standard test method.
